Automatic annotation interruption via mismatched request IDs
Published Aug 11, 2026 · Updated Aug 11, 2026
Denial of service in CVAT 2.17.0 through 2.71.0 allows remote authenticated users to block automatic annotation for a known task. RequestViewSet.create accepts a batch request whose task ID differs from its writable job ID and uses the unchecked task ID to reserve the task's single active request slot. Write access to any CVAT job and knowledge of the target task ID are required; the consequence is limited to interrupting automatic annotation on that task.
